What is CVE-2026-92462?

The yshop-crm application, up to version 2.1.3, contains a flaw that permits authenticated back-office users to invoke the DELETE /admin-api/crm/flow/delete-step endpoint without proper authorization. This oversight allows users to remove critical approval workflow steps necessary for managing contracts, receivables, and invoices securely. By failing to enforce necessary authorization checks on the CrmFlowController, the system leaves itself open to exploitation, where any user with access can disrupt essential business processes.

Affected Version(s)

yshop-crm 0 <= 2.1.3
